looking to redo the top end on my warrior, l was thinking a je 85mm 10.5:1 piston, and for the head i was thinking P&p, with a web 430 with hd springs, but i wasnt sure if the +1 valves are worth it?
and for carb i was thinking the Duncan racing 38mm kit.
what do you guys think?
 
With that piston and cam, the +1 valve might be a good idea. As for the carb, I've never ran one but some of the other guys might know. I'd run a FCR37 if it was mine. Btw, it will probably be mostly a top end motor. It won't have as much power in the low rpms.

thanks alot, does the fcr37 come with the engine flange? and it i went with the web 390 instead, with the +1 valve would that make it a more mid range engine?
